[ESP32-LyraTD-MSC V2.1] Send audio over TCP

[maryvpa]

Hello all,

I have the following issue, I need to send a voice recording from my ESP32-LyraTD-MSC V2.1 to a TCP server.
I can use the API to create an audio pipeline and link the I2S stream to capture the audio from the mic array but I can't figure out how to send that audio over a simple TCP connection...

Can anyone give any tip or advice?

Thanks in advance!

Cheers!

Perhaps the "Recording WAV file and upload to HTTP Server" example provides some useful ideas.

Thank you for your reply! I started my project based on this example, but this uses the HTTP stream already available on the API and doesn't help me so much with my goal of using a simple TCP socket where I can send only the audio that I want without any extra headers.

It seems that the raw audio over HTTP example is broken for the ESP32-LYRATD-MSC. Can anyone chime in on how to to get it working for the LYRA? Apparently it has to do with the Lyra using a different codec chip.

Did you managed to solve the issue? I am also interested in sending audio data using TCP.
